Pharmacokinetics of Efavirenz in HIV-1 Infected Subjects With Hepatic Impairment

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.

Participants were administered a dose of 600 mg once daily (capsules or tablets) of efavirenz, either in the morning (at approximately 9:00 AM) or before bed time (at approximately 9:00 PM), on an empty stomach. The duration of efavirenz administration was 2 days and participants were admitted to the clinical facility for this period. Mild hepatic impairment (grade A) is defined as a Child-Pugh (CP) total score of 5-6. The CP classification assesses 5 hepatic parameters (total serum bilirubin, serum albumin, prothrombin time, ascites and encephalopathy) on a scale of 1 (mild or none) to 3 (most severe). Total score range is 5 (mild) to 15 (severe).

EFV600mg Participants With Moderate Hepatic Impairment

Participants were administered a dose of 600 mg once daily (capsules or tablets) of efavirenz, either in the morning (at approximately 9:00 AM) or before bed time (at approximately 9:00 PM), on an empty stomach. The duration of efavirenz administration was 2 days and participants were admitted to the clinical facility for this period. Moderate hepatic impairment (grade B) is defined as a CP total score of 7-9.

EFV600mg Participants With Severe Hepatic Impairment

Participants were administered a dose of 600 mg once daily (capsules or tablets) of efavirenz, either in the morning (at approximately 9:00 AM) or before bed time (at approximately 9:00 PM), on an empty stomach. The duration of efavirenz administration was 2 days and participants were admitted to the clinical facility for this period. Participants who were on an off-label reduced dose of efavirenz (eg, 400 mg) continued on the reduced dose. Severe hepatic impairment (grade C) is defined as a CP total score of 10-15.

EFV600mg Participants With Normal Hepatic Function

Participants were administered a dose of 600 mg once daily (capsules or tablets) of efavirenz either in the morning (at approximately 9:00 AM) or before bed time (at approximately 9:00 PM) on an empty stomach. The duration of efavirenz administration was 2 days when participants were admitted to the clinical facility. Participants were enrolled after at least 6 participants with hepatic impairment had completed. One participant enrolled twice in the study and is hence counted twice in this group

Number of Participants Who Died or Experienced Other Serious Adverse Events (SAEs) [ Time Frame: From screening (within 21 days of Day 1 dosing) to the study discharge day (Day 2 for AM dosing or Day 3 for PM dosing). Participants were monitored for SAEs up to 30 days after study discharge. ]

Number of Participants Who Died or Experienced Other Serious Adverse Events (SAEs)

Measure Description

An SAE was defined as any adverse event (AE) occurring at any dose that; resulted in death; was life threatening; resulted in a persistent or significant disability/incapacity; resulted in/prolonged an existing in-patient hospitalization; was a congenital anomaly/birth defect; was a cancer; or was an overdose.

Time Frame

From screening (within 21 days of Day 1 dosing) to the study discharge day (Day 2 for AM dosing or Day 3 for PM dosing). Participants were monitored for SAEs up to 30 days after study discharge.

Population Description

Explanation of how the number of participants for analysis was determined.
Includes whether analysis was per protocol, intention to treat, or another method.
Also provides relevant details such as imputation technique, as appropriate.

All data from participants who signed the informed consent and enrolled in the study is included in the data set used for evaluating SAEs.

Limitations of the study, such as early termination leading to small numbers of participants
analyzed and technical problems with measurement leading to unreliable or uninterpretable data

The study was terminated early leading to a small number of participants treated and analyzed. Due to the small sample size, no conclusion could be made for participants with Child-Pugh scores B and C (moderate and severe hepatic impairment).

Principal Investigators are NOT employed by the organization sponsoring the study.

There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts
the PI's rights to discuss or publish trial results after the trial is completed.

The agreement is:

The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release
and can embargo communications regarding trial results for a period that is less than or equal to 60 days.
The sponsor cannot require changes to the communication and cannot extend the embargo.

The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release
and can embargo communications regarding trial results for a period that is more than 60 days but less than
or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.

Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed.

Restriction Description:
Bristol-Myers Squibb Co. agreements with investigators vary; constant is our right to embargo communications regarding trial results prior to public release for a period ≤60 days from submittal for review. We will not prohibit investigators from publishing, but will prohibit the disclosure of previously undisclosed confidential information other than study results, and request postponement of single-center publications until after disclosure of the clinical trial's primary publication.
